I've seen enough in the past two games to see that both of them are different in their own ways and both offer us different options.
I think come January or when Cahill is fit we just need a midfielder who can create something and both of them will be on form.
All i worry about at this moment in time is Johnson's confidence, just like Beatties 12 months ago when we brought in a new striker which piled the pressure on him.
He badly needs a goal and i think he offers so much to our team when hes his confidence is on top.
I think in the past two games they have shown a great understanding and know each other's strengths and more Yakubu but he knows exactly where Johnson is and his first touch is excellent.
